C++ Template Specialization (模板特化) 个人理解这个东西说白了就是当模板类(或函数)的类型参数为某特定值时用对应的特化定义代之。 看个例子吧 #include <iostream>usingnamespacestd; template<typename T>structis_void {staticconstboolvalue =false; };/*上面的代码定义了一个简单的模板结构is_void的主版本...

所谓模板特例化即对于通例中的某种或某些情况做单独专门实现,最简单的情况是对每个模板参数指定一个具体值,这成为完全特例化(full specialization),另外,可以限制模板参数在一个范围取值或满足一定关系等,这称为部分特例化(partial specialization),用数学上集合的概念,通例模板参数所有可取的值组合构成全集U,完全特例化...
When all of the template parameters are specialized, it is called afull specialization. When only some of the template parameters are specialized, it is called apartial specialization. In order to use a specialization, the compiler must be able to seethe full definition of both the non-specializ...

// partial specializations are allowed in this scope template < int K, void* NOT_USED > struct inner<I,K,NOT_USED> { static void foo() { std::cout << "partial specialization: outer<" << I << ',' << J << ">::inner<" << K << ',' << K << ">::foo\n" ; } }; ...
Partial Template Specialization 顾名思义,模版偏特化就是对模版进行特化的意思。 举个例子: namespaceSHFTest { template< classPLA, classPLB > classPLClass { // //一般实现 // public: PLClass() {}; ~PLClass() {}; voidFuncA() {
